Hi,
You can also weld RU8 like on Talonmotorsport's uprights. Here is a picture of the ones I bought from him. I guessed the upper part is leaning backward, and lower part frontward, so you have room for the hand-brake cable, and the bleeder of the wheel cylinder is still higher than the port. It also allows you, I think, to fit flexible brake lines with a straight male fitting (drum end) without any other transformation, extra bracket/copper pipe, and so on, which actually a big upside too.
Hope this will help.
Bye.
Sylvain
